Product Description

E4303 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes

LT·J422 Conform to Standard GB/T 5117 E4303

ISO 2560-B-E 43 03 A


Specification:Welding electrode E4303 (J422) is rutile-calcium based carbon steel welding electrode. It has excellent welding performance and mechanical properties that enables to operate on AC/DC, perform all-position welding. It is featured with stable arc, small spatter, easy slag peeling and arc re-striking. Weld bead is smooth and clean. It is flexible in weld ripple width and thickness.

 

Purpose:GB E4030 is used for welding of low carbon steel structure and low strength grade of low alloy steel structure. Such as Q235, 09Mnv, 09Mn2 etc.
